VORE BUCKET, DUMPER, AND CHUTE;

SPECIFICATION forming part of Letters Patent No.-700,7f41, dated May 27, 1902. Application filed February 4, 1902. Serial-No. 92,554. (No model.)

To @ZZ whom, it may concern.-

Be it known that I, LOUIS COLLIER, a citizen of the United States, residing at Cripplecreek, in the county of Teller and State of Colorado, have invented a new and useful Ore Bucket, Dumper, and Chute, of which the following is a specification.

My invention is an improved ore bucket, dumper, and chute adapted for use in con- Io nection with the hoisting apparatus used for raising an ore-bucket from and lowering the same into a mining-shaft, but also adapted to be used in other connections and for handling other material than ore, and is an improvement on the ore bucket, dumper, and chute for which Letters Patent of the United States, No. 677,560, were granted to me July 2, 1901.

One object of my present invention is to efzo fect improvements in lthe construction of the upper pivoted chute-section which overturns the ore-bucket and discharges the contents thereof.

A further object of my present invention is to eect improvements in the means for operating the saidupper pivoted chute-section.

A furtherobject of Vmy invention-is to provide the chute with a trap and means to operate the same.

A further object of my invention is to provide improved means for limiting the movement of the upper pivoted chute-section.

With these and other objects in view my invention consists in the peculiar construction 3 5 and combination of devices hereinafter fully described-and claimed. Y

In the'ac'comp'anying draWings,'Figure 1 is a side elevation, partly in section, of a hoisting apparatus for mining-shafts, provided 4o with an ore bucket, dumper, and chute embodying my improvements. Fig. 2 is a detail sectional View of the bucket, dumper, and

chute, showing the upper pivoted section thereof in the position assumed by said section when dumping the bucket. Fig. 3 -is a rear elevation of said pivoted dumping-section and of the means for actuating the same. Figs. 4, 5, and 6 are detail perspective views showing modifications of the means for connecting the dumping-'sectionfto the gallowsframe and limiting the p'lay of `said dumpingsection. Fig. 7 is a detail elevation showing a Amodification of means for limiting the play ofthe dumping-section.

The gallows-frame 1, which rises above the mouth of the shaft, is here shown as provided with four corner-posts 2, the lower ends of which are secured on sills 5, that form a ground-frame, and the upper ends of which areconnected together by plates 4. A pulley 5 has its bearings on a pair of cross-bars 6, which connecttheplates 4. The hoistingcable 7, which raises and' lowers the bucket 8, is operated bya hoisting-engine, (not here vshown,) which, as usual, is disposed at some distance from the mouth of the shaft. y The construction of thebucket is fully described in the Letters Patent hereinbefore mentioned. A chain 9 depends from the lower end of the bucket, and to the lower end of the chain is attached a'spherical or othery suitable form of button or stud 10. The gallowsframe is here shown as provided on theY side adjacent the hoisting-engine-with braces 11. Within the scope of myinvention the gallowsframe may be .of 'any suitable construction, and I do not limit. myself in this particular.

O'n one side'of the'gallows-frame is secured the lower iixed'section 12 jofthe'chute, the same comprising a bottom and sides. The bottom of the chute has an opening 13, in which is disposed a trap 14. The latter has its vertical sides 15 disposed within the sides of the chute 12 and bearing against the same and pivoted thereto'by bolts 16."` .The length of the bottom ofthe trap somewhat exceeds that of the'opening 13 in thebottom of the chute, sc that .whenthe' trap lis closed, as shown in full linesin Fig. 2, the lower end thereof rests .on the`bottom of the chute, while the upper end thereof rests under thebottom of the chute. A bell-crank 17 is fulcrumed to the gallows-frame, as at 18. One arm of the bell-crank isconnectedfto4 the trap by a link 19, the other arm ofthe bell-crank being connected to an operating-rod 20, which is supported by suitable guides 21 and extends to within convenient reach of the engineer at the hoisting-engine. The said operating-rod has suitable stops 22, by means of which it may be secured when it has been operated to set the trap in either position desired. At the upper end of the chute is the dump-section 23. The same is pivoted at its lower end, as at 24, and may be constructed of any suitable material. On the bottom of the dump-section are secured guide-bars 25, with their ends secured to said section and their body portions opened therefrom.

A rock-shaft 26 is journaled in bearings 27 on one side of the gallows-frame and has a crank 28, which extends transversely across the rear side of the dump-section and lies between the latter and the guide-bars 25, so that by turning the rock-shaft the dump-section may be turned either to an approximately vertical position, as shown infull lines in Fig. 2, or disposed in the plane of the chute 12 at'the upper end of the latter, 'as indicated in dotted lines inFig. 2. The rock-shaft has a weighted arm 29 at one end and a cross-arm 30 at the opposite end. A similar cross-arm 31 is pivotally mounted at a point near the hoisting-engine, where it may be readily operated by the engineer, and is connected to the cross-arm4 30 by suitable cords, rods, or other connecting elements 32, whereby the dump-section may be turned by the engineer to either position.

On the rear side of the dump-section vis a frame 33, which may be of the for-in here shown or of other suitable construction and in the present instance is constructed of a piece of T-rail bent to form the V-shaped arms 34, within which the guide-bars 25 are disposed, and the intermediate portion 35,

' which projects beyond the outer end of the d ump-section and has the rentrant V-shaped portion 36, that in edect forms a notch on the outer end of the dump-section to engage the button or stud 10 on the lower end of the chain 9, that hangs from the bottom- 'of the ore-bucket.

In the form of my invention shown in Figs. 1 and 2 chains 37 have their upper ends attached to bars 38, with which the gallowsframe is provided and which are at some distance above the chute. lThe lower ends of said chains are attached to the upper corners of the frame 33, and thereby connected to the chute. The length of the chains is such that while they permit the dump-section to be moved to either of the positions illustrated in Fig. 2 they limit the play of the dump-section, as will be understood.

4In Fig. 4 of the drawings I show another means for limiting the play of the dump-secsection, which I will now describe. A linkarm 37, which is V-shaped, is formed with a slot 39. The upper ends of the side members of the link-arm are screw-threaded, disposed in openings in a pivoted head 40 and adjustable in and secured to said head by taps 41. A traveler-block 42 operates in the slot 39, and the dump-section is connected to the traveler-block by a pivot stud or pin 43. A clamp 44 prevents the sidemember of the link-arm 37a from spreading. It will be understood that the pivot for the head 40 may project from one of the corner or cross bars of the gallows-i'rame.

In Fig. 5 of the drawings I show another modified means for limiting the play of the dump-section, which consists of a swinging link-arm 37b, having a slot 39", in which the pin 43 operates to connect the dump-section to said link-arm. In practice said swinging link will be suitably pivoted at or near its upper end to the gallows-frame.

lIn Fig. 6 of `the drawings I show another modiiied means for limiting the play of the dump-section, which consists of a swinging` link 37C, comprising an upper section 37d and a lower section 37e, pivoted thereto by a stud or pin 37f, which operates in a diagonal slot 37g in the upper portion of the said lower section 37e. The stud or pin 43 of the dumpsection operates in an opening 37. In practice said swinging link will be suitably pivotedat or near the upper end to the gallowsframe.

In Fig. 7 of the drawings I show another modified means for limiting the play of the dump-section, which comprises an arm 37, having a curved slot 37k,`concentric with the pivot 24 of the dump-section, and inl which curved slot they stud or pin 43 of the dumpsection operates. The said arm'37 is shown as attached to one of the corner-posts of the gallows-frame.

The operation of my invention is as follows: When the loaded bucket has been hoisted to a point above the dump-section of the chute, as shown in Fig. v1, the dump-section, which is normally by the weightedv arm of the rockshaft 26 pushed out of the path of the bucket, as shown in full lines in Fig. 2, is by the engineer turned so that its upper end is disposed under the bucket, as shown in Fig. 1. This is done by means of the cross-arm 31 and the connections, hereinbefore described, between the same and the rock-shaft. The engineer then causes the cable 7 to be slackened to lower the bucket sufficient to allow the bottom of the bucket to rest on the rear notched end cf the dump-section, which has been so placed; that its extreme rear end strikes the bottom of the bucket at a point on the inner side of the center of gravity thereof, and as the cable is further slackened the bucket is tilted by its own gravity in the direction of the fixed chute and inally descends therein in an inverted position, as shown in full lines in Fig. 2,- thereby discharging its contents intovthe chute. As the bucket descends in the pivoted dump-section the vchain 9, attached to the bottom thereof, engages and passes through the notch 36 until the button 10 engages the sides of said notch and arrests the descent of the bucket in the chute. The

,bucket is then hoistedto a position above the dump-section, andthe latter as soon as it is roo IIO

disengaged by the bucket is by the weighted arm of the rock-shaft 26 turned out of the path of the bucket, when the latter is lowered in the shaft to be reloaded. It will be understood that the action of the dump-section with reference to the bucket is such as to invariably cause the bucket to tilt away from the shaft and discharge its contents into the chute, so that none of the contents of the bucket can fall back into the shaft.

As is well known, the dumping of ore-buckets by means of the trip-rope commonly used causes the bucket to dump toward the shaft withdanger of some of the contents falling into the shaft and injuring men below. My improved ore-bucket, dumper, and chute obviates this objection and enables the engineer in charge of the hoisting-engine to operate the bucket in such manner as to dump its contents safely. It is often important that the buckets be dumped at a considerable elevation-say from twenty to forty feet above the surface--in order to allow the ore or other material to be discharged by the chute onto the dump or int suitable bins by gravity. Under existing methods and by the means commonly employed for hoisting ore-buckets a top man must be stationed at the dumping-point to dump the bucket. It will be understood that my invention enables the bucket to be dumped with ease and entire safety by the engineer in charge of the hoisting-engine and the services of the top man to be dispensed with.

Having thus described my invention, I claim- Y p 1. In combination withahoisting means and a tilting bucket raised and lowered thereby, said bucket having a button suspended from its bottom, a ixed chute having a trap in the bottom thereof, means to operate the trap, a pivotally-mounted dump-section at the upper end of the chute, said dump-section having means to coperate with the button and dump the bucket, and means to set the pivotal dump-section, substantially as described.

2. In combination with ahoisting means and a tilting bucket raised and lowered thereby, said bucket having a button suspended from the bottom, a chute, a pivotally mounted dump-section at the upper end of the chute and having means to coperate with the button and dump the bucket, a rock-shaft hav-l ing a crank connected to the dump-section, and provided further with a weighted arm to move the dump-section out of the path of the bucket, and means to move the dump-section into the path of the bucket, substantially as described.

3. In combination with a hoisting means and a tilting bucket raised and lowered thereby, a chute, a dump-section pivotally mounted at the upper end of the chute, said dump-section and bucket having coacting means to tilt the latter and dump its contents into the chute, a rock-shaft having a crank connected to the dump-section and a weighted arm to normally turn the dump-section out of thevpath of the bucket, and means, connecting the dump-secltion to a fixed point, to limit the play of the dump-section, substantially as described.

In testimony that I claim lthe foregoing as my own I have hereto affixed my signature in the presence of two witnesses.

LOUIS COLLIER.
